"Shi Shuo Xin Yu" records Shi Chong and Wang Yu fighting the rich, Wang Yu to Shi Chong show off the two-foot-high Yuci Coral Tree, but Shi Chong took the iron and shredded it, and took out the number of coral trees three or four feet high. Piece, Ren Wang took it. Although it is a story of showing off the rich, it also shows the precious and long history of coral collection. The caps and pilgrimages worn by the Qing Dynasty's second-grade officials were made of precious red corals; Tibetan sorghums held rosary beads made of red corals. In the western part of the 16th century, the red coral trade on the Mediterranean coast was very prosperous, creating many high-value red coral art masterpieces. It can be seen that the collection of corals should be suitable for the present and the west. Coral ranks among the three organic gems Corals, pearls and amber, which are called rare and expensive three natural organic gemstones, have always been loved by the world. The so-called organic gemstones are materials that are produced by natural organisms, partially or entirely composed of organic substances, and can be used for jewelry and decorations. In addition to pearls, corals and amber, as well as ivory, coal, tortoise shells, shells and silicified wood, etc., are important organic gems that nature has given to humans. Coral is a bone formed by the accumulation of calcium as the main body secreted by lower coelaceous coral polyps. Interestingly, the normal state of this skeleton is dendritic output, which is usually divided into two according to composition and color. There are five types of calcium, calcium type and keratin type. Calcium type is mainly calcium carbonate, which contains a very small amount of organic matter, which is subdivided into red coral, white coral and blue coral. The main component of horny coral is organic, including Gold coral and black coral. Corals can be divided into shallow sea corals and deep sea corals depending on the location of the growing sea. Shallow sea corals, also known as reef-building corals, are widely distributed. There are many small islands of coral reefs in the shallow waters of the Pacific Ocean, the Indian Ocean and the Atlantic Ocean. Hardness is less than 2, can not be used as a raw material for carving art, can only be used as a stone for viewing. The shallow sea corals that many people have placed are the shallow sea corals. Deep-sea corals, also known as precious corals, are generally found in corals with a depth of 200-2000 m. Their distribution in the world has certain limitations. Because its petrochemical process is completed in the deep sea, coral jade has a small pore size and a high density (generally between 2.5 and 2.8). The structure is dense and the hardness varies between 3-4, due to the red coral in the deep sea coral. The most precious, therefore, red coral has become synonymous with valuable corals. Production scarcity value soars Corals grow slowly, 20 years and an inch, only one kilogram in 300 years, and the red corals that are visible on the market need to be formed for thousands of years. Some people have used "Millennium Baby" to describe it. Due to over-exploitation in the past, the growth rate of corals is far behind the speed of mining. The harvesting of red corals in the world today is between 100 and 400 tons per year, and the price is often several times or even several times that of gold. At present, China has listed red coral pests as national first-class protected wild animals. The operation of deep-sea red coral products is more strictly regulated. It is necessary to apply for relevant business licenses issued by the Ministry of Agriculture, and it is not allowed to operate for sale without approval. The scarcity of production and the regulation of policies have directly led to the rise in the price of fine red corals on the market. The price of red corals has now reached several hundred to several thousand dollars per gram, the price of fine products is higher, and the price rises by 30% every year. The value of a good red coral necklace can reach hundreds of thousands of yuan. And the potential for appreciation is also growing. It is worth mentioning that in the primary market, there are often grades such as “AKA Coralâ€, “Aka Coralâ€, “MOMO Coralâ€, “Momo Coralâ€, and the top AKA coral market price is 20,000. About RMB per gram, the MOMO coral price is about several thousand yuan. In fact, these titles are popular in the primary market, but they are not accurate enough. They are not included in the systematic gemology textbooks, non-professional titles, but also the attention of investment collectors. These names are directly transliterated from the names of Japanese corals. AKA is originally intended to be red and refers to red corals. MOMO originally meant peach or peach color, broadly referred to as peach-colored coral; this grading and pricing can be used as a reference, but it must be noted that this title is not professional. Of course, the focus of red coral conservation is still on the color and volume. The more red, the more intense the color, the higher the price. The ancient saying "Millennium Coral Red" also means this; on the other hand, the larger the coral, the larger The longer the time is formed, of course the higher the value. New and old red corals have investment value Coral products in the current market are mostly divided into two categories: ancient and new. In the secondary market, the coral jewelry and ornaments auctioned by the auction company are mostly old coral items, while the first-class jewelry market sells many new coral products. From the point of view of collections, new works and old ones each have their own collection groups. Some people love old things, some people like new jobs, and both have investment value. In recent years, as coral prices continue to rise in the art market, more and more investors are looking at corals. At the 2010 Hanhai Autumn Auction in Beijing, a mid-season Mongolian coral headgear was sold for 2.8 million yuan. At the Sotheby's 2013 Autumn Art Auction in Hong Kong, a Qing Dynasty red coral snuff bottle of less than 7 centimeters was sold at HK$500,000. This snuff bottle is small and exquisite, and it is so delicate that it is so addictive. This type of coral ornaments, playing pieces frequently appear in the market this year, and the turnover is higher, showing a relatively fixed collection group. The quality of the new red coral jewelry new work, there are also good performance in the current market. With the promotion of Sotheby's and other international giant auction companies, domestic auction companies are paying more and more attention to jewelry auctions, and they have opened jewelry specials, and there are also some high-quality coral jewelry auctions. As early as 2005, Christie's Autumn Auction in Hong Kong launched a red coral set, a red coral bead chain, a coral ring, and a pair of earrings. The set of jewelry at that time was estimated at 8,000 yuan, but after multiple bidding, it was finally sold at 165,000 yuan. A red coral-studded brooch launched by Sotheby's in Hong Kong in 2008 was sold for HK$112,000. In 2014, China Merchants Shengjia launched a multi-layer coral bead chain with a turnover of 805,000 yuan. Beijing Rongbao a red coral necklace sold for 280,000 yuan. New workers and old ones have their own merits. The new crops are more advanced than ancient times in terms of mining, salvaging and carving, and the subject matter will be broader than in ancient times. For example, in ancient times, coral salvage was basically based on fishing trawling, and now the salvage of corals is used for submarine exploration in order to salvage better red corals. In terms of craftsmanship, the ancient corals have exquisite craftsmanship in addition to the palace decoration, and the folk craftsmanship is not as good as the present. However, the most popular in the auction market is the court decoration. This kind of coral ornaments will be popular when they are shot. It is worth noting that the choice of fine corals, both engraving and material. Nowadays, the number of precious red corals is scarce, especially some coral trees up to 2 feet tall. It is rare to have such a boutique, and there is considerable room for appreciation in the future. In addition, the size of coral jewelry is often one of the most important factors in determining its price. "Like diamonds, the bigger the price of red coral, the higher the price." Carving is another important factor affecting the price of coral. First, it depends on whether the engraver is good or not. The character’s words depend on whether it is correct and whether the expression is kind, while the animals and landscapes are to see if they are lifelike. The second is to see if the engraver is a famous person. If it is a sculptor, the price of the red coral is obviously Can not be the same as the price of the general engraver. For many collectors and investment enthusiasts, carefully designed and carefully crafted artworks and jewellery not only have considerable economic value, but also a collection of humanities, history and investment value, even if the investment value may be expressed in the short term. Not obvious, but in the long run, it is undoubtedly a good choice for investment collection.
